Abstract
Description
[Technical field]
[0001] The present invention relates to an aerial vehicle, and more particularly, in a preferred form, the present invention relates to an aerial vehicle having a gyroscopic fan with pivoting fan blades. [Background technology]
[0002] Any reference to prior art methods, apparatus, or documents should not be taken as constituting any evidence or admission that they form or form part of the common general knowledge. Since the invention of flight, many different forms of aircraft have been developed, for example helicopters, airplanes, etc. There are many different factors and forces involved in achieving stable, controllable flight, and different types of aircraft have different flight characteristics with various advantages and disadvantages.
[0003] For example, fixed-wing aircraft can be configured to fly long distances relatively quickly, but cannot fly slow or hover, and require long runways for horizontal takeoff and landing. Helicopters, on the other hand, can take off and land vertically and can hover, but are limited in size, and in the speed and distance they can travel. These characteristics make fixed-wing aircraft well suited for the long-distance transportation of relatively large loads, while helicopters are well suited for the short-distance transportation of relatively small loads, and for emergency rescue operations, where the ability to fly slow and hover is particularly advantageous. It would be desirable to provide aircraft with different, preferably wider, characteristics, combining advantages and / or minimizing disadvantages.
[0004] One of the uses of aircraft is firefighting. Uncontrollable fires pose a serious problem today, with large fires ravaging forests, communities, industrial and commercial areas, potentially resulting in loss of forests, homes, other property, animals and even human lives. Efforts to contain the fires are not always successful. Controlling and preventing the spread of the fires is often difficult.
[0005] There are many known methods and techniques for controlling and preventing the spread of fire. Such methods include the traditional use of firefighters and equipment, including techniques such as dropping large amounts of water or extinguishing agents on a fire from aircraft, setting up firebreaks across the direction of fire advance, spraying water or extinguishing agents on the fire by firefighters on the ground, and burning areas near a fire in a controlled manner to effectively remove wood or other combustible material from the approaching fire.
[0006] The use of water or other extinguishing agents alone has been found to be ineffective against large fires. There is an assumption that once the fire intensity exceeds a certain threshold, the use of water or other extinguishing agents will be largely ineffective because the water or extinguishing agent will evaporate or dissociate before reaching the center of the fire. In view of these issues, it is also desirable to provide alternative methods for suppressing fires, especially large fires. Summary of the Invention [Problem to be solved by the invention]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0025] Figures 3, 18 and 19 show a first embodiment of an aircraft 100 configured to be gyroscopically stabilized in a manner described in more detail below. Figures 1 and 2 show a releasably attachable cockpit module 105 shown to be attached to an aircraft such as aircraft 100 to form aircraft 200, as shown in Figures 4-6. As best shown in Figures 5 and 6, aircraft 200 comprises a ducted fuselage 210 including an opening in which a jet turbine 250 is disposed to provide a propulsion mechanism. Suitable engines that can be used to generate the exhaust include pulse jet engines, turbojet engines, turbojet engines with afterburners, axial turbojets, gas turbine propulsion engines, rocket engines, turbofan aircraft engines, low bypass turbofans, high bypass turbofans, turboprops, ramjets, turboshaft engines, underwater jet engines, shock wave triple engine jet trucks, and the like. A combination of different types of engines can also be used.
[0026] The jet turbine 250, located in an opening in the fuselage 210, preferably functions similarly to other jet turbines, whereby air is drawn in by the turbine and a compressor increases the pressure of the air. The compressor is made of many blades attached to a shaft assembly 260. The blades rotate at high speeds, compressing or squeezing the air. Fuel is then blown into the compressed air, igniting the mixture with an electric spark. The combustion gases expand and eject from an exhaust nozzle 255 at the rear of the engine. As the jet of gases is fired backwards, the engine and aircraft 200 are thrust in the opposite direction (upwards with respect to FIG. 5). As the hot air heads towards the nozzle 255, it passes through another set of blades, called a turbine. The turbine may be attached to the same shaft assembly 260 as the compressor, and rotating the turbine rotates the compressor.
[0027] In this embodiment, the fuselage 210 of the aircraft 200 is shown attached to the aircraft frame 245 and has a particular shape that is generally symmetrical about an axis. However, the shape of the fuselage 210 should not be considered limiting, and the shape of the fuselage 210 may vary in other embodiments. The jet turbine 250 drives a shaft assembly 260 that is also coupled to a gyroscopic stabilization assembly that includes the gyroscopic fan 240. The gyroscopic fan helps stabilize the aircraft 200 during flight.
[0028] The blades of the gyroscopic fan 240 are arranged around a central hub coupled to a shaft assembly 260. The blades of the gyroscopic fan 240 are alternating pivoting fan blades that change the angle of the fan blades as needed to provide the necessary stabilization to the aircraft 200. In a preferred embodiment, the longitudinal axis of the fuselage 210 extends longitudinally through a duct opening along the shaft assembly 260, which also drives the blades of the gyroscopic fan 240. The gyroscopic fan 240 includes a number of blade members, which are preferably variable pitch blades, such that the pitch of the blades can be changed by pivoting the blade members. As the blade members are variable pitch, i.e., each blade member can pivot about its longitudinal axis (its pitch axis) to adapt the orientation of its leading edge to the engine speed. Thus, the orientation of the blade members (also called the pitch setting) constitutes one of the parameters to facilitate managing the thrust of the jet turbine 250.
[0029] A controller is also provided for controlling the gyroscopic stabilization via the gearbox such that the angular momentum provided by the gyroscopic stabilization (particularly the fan blades of the gyroscopic fan 240) is significantly greater than the moment of inertia of the aircraft 200 such that the aircraft 200 is substantially gyroscopically stabilized during flight.
[0030] The provision of gyroscopic stabilization in combination with the jet turbine 250 provides a vertical take-off and landing (VTOL) aircraft 100, 200 (and aircraft 300, 400 described below). By providing an aircraft with VTOL capabilities, the aircraft 100, 200, 300, 400 may be used in a variety of situations including, for example, firefighting, particularly where access to or delivery of firefighting media to an area would otherwise prove difficult, impossible or dangerous.
[0031] The gyroscopic stabilization system is preferably configured to provide sufficient angular momentum with sufficient mass angular velocity such that the aircraft 100, 200, 300, 400 is gyroscopically stabilized during various phases of flight. In one embodiment, the fuselage may be fixedly attached to the jet turbine. In another embodiment, the jet turbine may be pivotally attached to the fuselage, particularly if the jet turbine exhaust nozzle needs to be aimed toward a fire front, etc.
[0032] In a preferred embodiment, the fuselage 110 is adapted to allow the aircraft 100, 200, 300, 400 to land and take off in a vertical take-off and landing (VTOL) profile. In particular, an undercarriage assembly including landing gear in the form of landing struts allows the aircraft to take off from a surface with the plane of the fan blades of the gyroscopic fan substantially parallel to the plane of the ground, and allows it to land in a similar manner. In a preferred embodiment, the fuselage may be pivotally or movably fixed to the aircraft frame, allowing relative movement between the fuselage and the aircraft frame.
[0033] The aircraft 100, 200 may also include annular wing flaps 115, 215 that may be attached to the outer sides of the fuselage. The annular wing flaps 115, 215 may also provide additional flight surfaces to facilitate horizontal flight of the aircraft 100, 200 (as shown in Figures 3-6). Also, in a horizontal flight configuration, the plane of the gyroscopic stabilizer is substantially perpendicular to the plane of the ground, as shown in Figure 6. However, from the following description, those skilled in the art will appreciate that the provision of flight surfaces and annular wing flaps 115, 215 may be optional.
[0034] As previously described, the aircraft 100, 200 includes a gyroscopic stabilization system that gyroscopically stabilizes the aircraft 100, 200 throughout the flight envelope. The use of gyroscopes results in a more stable aircraft and stable flight characteristics, which is very important for flexible and versatile flight characteristics for various applications, such as fire suppression. Each blade member of the gyroscopic fan 240 is attached to a rotating propeller shaft, which is coupled to a shaft assembly 260. This allows sufficient angular momentum to be generated so that the aircraft is gyroscopically stabilized when an external or internal moment is applied to the aircraft, such that the resulting force of the moment is converted into gyroscopic precession. Larger aircraft with larger motor sizes and improved performance require larger gyroscopic stabilizing members and / or gyroscopic stabilizing members that rotate at higher angular velocities to gyroscopically stabilize the aircraft. Similarly, smaller and lighter aircraft require smaller and lighter gyroscopic stabilizing members.
[0035] The aircraft 200 may also include a cockpit module 105 that is preferably coupled to the frame of the aircraft 200 via a removable coupler 220. The cockpit module 105 includes a counterbalance device for balancing the cockpit module 105 against the movement of the fuselage 210 and / or the exhaust of the jet turbine 250. In the embodiments described herein, the cockpit module 105 may include a gimbal-like mechanism that allows the cabin 106 of the cockpit module 105 and its occupants to be positioned in a substantially upright position during all periods of flight, including both vertical takeoff and landing (as shown in FIG. 5 ) and horizontal flight (as shown in FIG. 6 ) of the aircraft 200. The cockpit module 105 may include navigation and flight controls for controlling the aircraft 200 and may also address several safety requirements.
[0036] In a preferred embodiment, the cabin 106 of the cockpit module 105 is pivotally mounted to the gimbal ring 125 at mounting points 135 to rotate about a first axis. As shown most clearly in FIG. 2, the gimbal ring 125 is attached to the aircraft frame 145 at mounting points 130 to allow rotation about a second axis, thereby causing the cabin 106 of the cockpit module 105 to roll or pitch, thereby applying a counterbalancing force to the cockpit module 105. In FIG. 5, the cockpit module 105 is shown in a first upright position when the aircraft 200 is in a takeoff or landing position. In FIG. 6, the cockpit module 105 is shown in a level flight position, and it can be seen that the cabin 106 of the cockpit module 105 is in an upright position even though the cockpit module 105 itself is rotating.
[0037] In a preferred, but by no means required, embodiment of the fire suppression of the present invention, the exhaust may be obtained from one or more jet turbines or jet engines. As used herein, the term "jet turbine" refers to a turbine that accelerates and expels a jet of fast moving fluid, e.g., gas such as exhaust gas, to generate propulsion or thrust for an aircraft. In a typical jet engine, air from an intake is directed to a rotating compressor where it increases in pressure and temperature. The compressed air is introduced into a combustion chamber where it is combined with fuel and the mixture is ignited. Combustion increases the temperature of the gases, which expand through a turbine. In the turbine, a portion of the temperature increase is converted to rotational energy that can be used to drive the compressor. The combustion gas mixture (generally devoid of oxygen) exits through an exhaust induction assembly that includes an exhaust nozzle 255.
[0038] Preferably, the turbine is a gas turbine, which functions like a windmill to extract energy from the hot gases exiting the combustor. Suitable types of turbines that can be utilized include transonic turbines, counter-rotating turbines, statorless turbines, ceramic turbines, shrouded and shroudless turbines, and others known in the art. Microturbines can also be used in at least some embodiments.
[0039] The exhaust nozzle 255 may be of the convergent-divergent type, divergent type, fluid type, variable-flow type, e.g., ejector nozzle, iris nozzle, or other suitable type. In general, jet turbine exhausts and exhaust nozzles such as nozzle 255 are characterized by their temperature, chemical composition, velocity, delivery volume, delivery rate, pressure, and other parameters such as noise, air quality, etc. The exhaust from a jet engine can reach temperatures of several hundred degrees, requiring air-cooled protection of the piping and exhaust nozzle.
[0040] The exhaust from such aircraft is believed to be particularly well suited for use in suppressing fires using the exhaust generated by one or more engines, preferably jet engines. More specifically, the invention relates to using the exhaust to suppress fires, such as forest, residential, commercial or industrial fires on the ground. As with fires, it is also possible to suppress or extinguish explosions.
[0041] The exhaust gas from a jet turbine, in terms of its chemical composition, generally consists of combustion products (e.g., carbon dioxide (CO2), carbon monoxide (CO) and water (HO)), unburned gases (e.g., nitrogen gas (N2), oxygen (O2), unburned hydrocarbons (UHC), and soot (C), oxides of nitrogen (NO X ) and / or sulfur oxides (SO X), among other components. Compared to the atmosphere at sea level, which contains nearly 21% oxygen (O2) and about 0.03% carbon dioxide (CO2) by volume, jet engine exhaust gases are low in oxygen and high in carbon dioxide. For example, the pressurized exhaust from the complete combustion of a hydrocarbon fuel in an efficiently operated turbine engine consists of about 72% carbon dioxide gas by volume and about 27.6% steam by volume. As a result, the chemical composition of the exhaust gases plays an important role when the aircraft 100, 200 is utilized to control or extinguish a fire by directing the exhaust nozzle 255 at the fire. The ratio of air to fuel can be manipulated by the use of a throttling mechanism, dilution with inert gases, or other means, which further reduces the oxygen concentration in the exhaust and improves the fire-fighting capabilities of the aircraft 100, 200.
[0042] As explained above, the use of a jet turbine directs a jet of gases away from the aircraft 100, 200 at very high speeds. During firefighting operations, if there is a significant distance between the jet turbine 150 and the fire front, or between the leading edge of the fire and the jet turbine 150, the jet turbine must be able to generate exhaust pressures high enough to blow a significant amount of the exhaust gas mixture onto the fire from such distances. As an example, the Pratt & Whitney JT8-JT30 series turbines can provide enough thrust to fly the aircraft 100 and also can exhaust gases at a sufficient velocity to extinguish the fire. Practical considerations may be necessary, such as not running the jet turbine at 100%, particularly during firefighting operations, to control the temperature of the exhaust gases. It should also be noted that other turbines that are adequate for the job under the current conditions may provide a different range of exhaust pressures to provide the desired fire suppression capabilities.
[0043] Advantageously, the turbine 250 may be mounted on a support that not only supports the turbine 250 but also allows the turbine 250 to move in multiple directions. In at least some embodiments, the support can rotate the turbine 360 degrees. A steering assembly is coupled to the support and may be controlled by the aircraft operator to control the orientation of the jet turbine 250 to direct exhaust gases in a desired direction for fire suppression.
[0044] As shown in Figure 18, multiple such aircraft 100 may be used to perform firefighting operations. As shown in Figure 19, two (or more) such aircraft 100 may be coupled in tandem by providing attachment ports so that multiple such aircraft 100 may be coupled together.
[0045] 7-17 show another embodiment of the aircraft 300. The aircraft 300 is also adapted to be gyroscopically stabilized by a stabilizing device including a gyroscopic fan 335 with variable pitch blades. The gyroscopic fan 335 is disposed in a plane perpendicular to the longitudinal axis of the jet turbine 340. The gyroscopic fan 335 is coupled to the jet turbine 340 by a shaft assembly 350 that transfers power from the jet turbine 340 to the gyroscopic fan 335. The gyroscopic fan 335 may be coupled to the jet turbine 340 by one or more other methods, and a shaft as shown may not be required in some embodiments. In a preferred embodiment, the shaft assembly 350 may include one or more gear mechanisms for controlling the operation of the gyroscopic fan 335. In other embodiments, the gyroscopic fan 335 may be coupled to the jet turbine 340 by electronic or other mechanical configurations.
[0046] The aircraft 300 is also adapted to be gyroscopically stabilized in the manner described above. The aircraft 300 also includes a ducted fuselage 345 including an opening in which a jet turbine 340 is disposed to provide propulsion. The aircraft 300 includes a wing flap 325 adapted to pivot about a pivot point 315. The aircraft 300 also includes an articulated front wing 320 adapted to pivot about a pivot point 365.
[0047] The aircraft 300 also includes a pivoting cockpit module 310 (providing an egg-shaped "pod" enclosure) adapted to pivot along two different axes. Specifically, the cockpit module 310 is adapted to pivot about a pivot point 330A to allow the cockpit module 310 to pivot along a first axis (roll). The cockpit module 310 is also adapted to pivot about a pivot point 330B to allow the cockpit module 310 to pivot about a second axis (pitch). Providing the cockpit module 310 allows the aircraft 300 to be operated by a pilot or the like during flight.
[0048] The aircraft 300 may also be associated with the use of exhaust generated from the jet turbine 340 for fire suppression. The jet turbine 340 provides thrust to the aircraft 300. In use, an air intake on the engine draws in ambient air and the combusted air-fuel mixture is discharged from the exhaust 360 and exits through the exhaust 360 at high velocity. An airflow directing assembly including an exhaust nozzle may be used to direct the combusted air-fuel mixture from the exhaust 360 in a desired direction for fire suppression.
[0049] 20 and 21 show a further embodiment of the aircraft 400 in which the body is annular with a torus (or "doughnut") shaped fuselage 445. A plurality of jet turbines 440 are mounted on the sides of the torus fuselage 445 primarily for propulsion and / or lift purposes. The plurality of jet turbines 440 mounted on the sides of the torus fuselage 445 may be rotatable at least 90 degrees to enable vertical take-off and landing (VTOL) capability. A gyroscopically stabilized jet 450 may be mounted inside the torus fuselage 445. A gyroscopic fan 435 is located in the center of the torus fuselage 445. A cockpit module 415 may be located inside the torus fuselage 445 to enable accommodation of crew and / or passengers. The torus fuselage 445 may also be loaded with cargo.
[0050] Advantageously, the present invention provides a versatile aerial vehicle (100, 200, 300, 400) having many useful and versatile flight characteristics, including, for example, an aircraft with VTOL capabilities and gyroscopically stabilized flight during takeoff and landing. As previously identified, one particular application of interest is firefighting. However, such an aircraft may also be used for transportation and rescue operations. Additionally, embodiments of the aircraft may be used to land on other planets, provided they have a suitable atmosphere. The use of gyroscopic disks instead of gyroscopic fans may also ensure stabilization of spacecraft and / or satellites in atmosphereless outer space.
[0051] In accordance with the statute, the invention has been described in terms more or less specific indicating structural or methodological features. The term "comprises" and variations thereof, such as "comprises" and "includes," do not exclude additional features, but are used throughout in an inclusive sense.
[0052] The invention is not limited to the specific features shown and described, since the implementations described herein are preferred forms for carrying out the invention. The invention is therefore claimed in any of its forms or modifications within the proper scope of the appended claims as appropriately interpreted by those skilled in the art.
